Time Narration
00:00 Welcome to the Spoken tutorial on LibreOffice Base.
00:04 In this tutorial, we will learn about * What is LibreOffice Base?
00:09 * Prerequisites for using Base
00:12 * What can you do with Base?
00:14 * Relational Database basics, Create a new database, Create a table.
00:20 LibreOffice Base is the database front-end of the LibreOffice suite.
00:26 Base is the equivalent of Microsoft Access.
00:30 Base is free and open source software, free of cost and free to use and distribute.
00:37 Let us look at the prerequisites for using 'Base'.
00:41 Following are the System requirements for Microsoft Windows:
00:45 Microsoft Windows 2000 (Service Pack 4 or higher), XP, Vista or Windows 7, Pentium-compatible PC up to 1.5 Gb available hard disk space.
01:02 For Ubuntu Linux, here are the System requirements:
01:06 Linux kernel version 2.6.18 or higher, Pentium-compatible PC.
01:13 For both, Windows and Linux installation, we require 256 Mb RAM (recommended 512 Mb).
01:24 For complete system requirements, visit the Libreoffice website.
01:30 You will also need to install Java Runtime Environment which you can download at the following link.
01:38 Click on the red button in the centre that says 'Free Java Download'.
01:44 Once the file is downloaded, double-click on it and follow the instructions to install.
01:52 Let us now look at LibreOffice Base installation:
01:56 If you have already installed 'LibreOffice Suite' with the complete installation option
02:03 then you can access LibreOffice Base by clicking on the Start menu at the bottom left of your screen.
02:12 Click on All Programs and then click on LibreOffice Suite.
02:21 If you have not installed LibreOffice Suite,
02:24 you can install Base by visiting the official website and clicking on the green area that says 'Download LibreOffice'.
02:37 Detailed instructions are available in the first tutorial of LibreOffice Suite.
02:43 Remember, when installing, use the Complete option to install 'Base'.
02:50 Okay, let us go to the next topic now.
02:54 What can you do with LibreOffice Base?
02:57 With Base - * you can store organized data
03:02 * perform data entries and view data using forms
03:08 * retrieve information using queries and
03:12 * design and generate nice, printer-ready reports.
03:17 Base helps you to manage databases.
03:21 As you may know, a database is a group of data, forms, queries and reports.
03:29 For example, 'Base' can be used to manage Customer Information databases,
03:36 track sales orders and invoices, maintain student grade databases or build a library database.
03:47 Let us now learn about some basics of databases.
03:51 A database has data stored and organized into tables.
03:56 Tables have individual pieces of data, stored in rows and columns.
04:03 Such a database is also called a relational database where the tables have relationships with each other using the columns.
04:15 Let us consider a simple database for a Library.
04:20 A library can be a collection of Books.
04:23 And books can be issued to members of the library.
04:28 A book can have a Title, an Author, a Publisher, Year of publication and a Price.
04:37 These are called characteristics or attributes.
04:42 Similarly, a Library member has a Name, Phone number and an Address.
04:48 And the library issues books to its members only.
04:54 Now, let us see how we can store this data as individual tables of rows and columns.
05:02 Information about each book can be stored in a Books table,
05:08 with its attributes becoming the columns: book Title, Author, Publisher, Year of publication and Price.
05:19 To distinguish each book, let us also add a unique identifier column called BookId.
05:27 This way, we can have two completely different books with the same title.
05:33 Similarly, a Members table can have columns like Name and Phone
05:40 and a Member Id to uniquely identify or distinguish each member. <pause>
05:47 And we can track the books issued to members in a third table called BooksIssued.
05:56 This table will track the book issued, the member, date of issue, date of return, actual date of return, whether checked-in or not.
06:09 We can establish relationships among these tables, to interlink the data in them.
06:16 Now, this helps us to manage relational databases.
06:22 For advanced topics on relational databases, refer to our other tutorials by visiting the website Spoken tutorial.org.
06:35 Okay, let us now get started with our first Base database called “Library”!
06:43 To create a new database, let us first open the Base program.
06:50 Then, click on the Windows Start menu at the bottom left of the screen. Then click on All Programs, then LibreOffice Suite and LibreOffice Base.
07:08 A pop-up window titled Database Wizard opens.
07:13 Click on the Next button to create a new database.
07:19 Click on the Finish button in the following window.
07:23 This opens a Save As window.
07:27 Since we are building a Library database, we will type "Library" in the File Name text-box
07:35 and then click on the Save button.
07:39 Now, we are in..
07:42 Next, let us create tables to store data.
07:46 To create a new table, click the Tables icon in the Database list on the left.
07:54 Click on the 'Create Table in Design View' in the Tasks list on the right. This opens another window.
08:05 Here, type "BookId" as the first column under Field Name.
08:13 Use the Tab key to move to the Field Type column.
08:18 Since the BookId will be a different number for each book, select Integer as the Field Type from the drop-down list.
08:32 Change the Field Properties in the bottom section.
08:36 Change AutoValue from "No" to "Yes".
08:41 This field now will uniquely identify each book.
08:46 In other words, this field is also called the Primary Key.
08:52 Notice the yellow key symbol to the left of the BookId field.
08:58 Let us see how we can choose Field Types for Field names.
09:05 Field types can be text, integer, numeric, decimal or date.
09:13 Use Text for fields that have general information, for example- name, title, address.
09:22 Use Integer, numeric, decimal for fields that may contain only numbers.
09:30 For example- use numeric for a field with price information, Integer for years.
09:39 Let us create the rest of the fields now.
09:43 Title- Field type: Text, Author-
09:52 Field type: Text, Published Year-
09:59 Field type: Integer,
10:05 Publisher-
10:09 Field type: Text,
10:11 Price-
10:14 Field type: Numeric.
10:18 Change the Length to 5 and Decimal places to 2.
10:25 Click the Format example button.
10:29 This opens the Field Format window.
10:33 Select Currency from the Category list and INR from the Format list.
10:42 Let us choose Rs. 1234.00 that has two decimal places.
10:54 Notice that the total length is five, inclusive of the two decimal places.
11:02 Click on the OK button. Now we have created all the columns for the Books table.
11:11 Let us now save the table.
11:14 Click on the Save icon that is below the File menu.
11:20 Type "Books" in the Table Name text-box.
11:25 Note that it is saved in the same location as the database ‘Library’, as tables are a part of a database.
11:36 And click on the OK button.
11:39 In the next tutorial, we will add data to the Books table and create the Members and BooksIssued tables.
11:50 This brings us to the end of this tutorial.
11:54 To summarize, we covered the following:
11:58 * What is LibreOffice Base?
12:01 * Prerequisites for using Base
12:03 * What can you do with Base? 'Relational Database basics'
12:08 * Create a new database, create a table.
12:13 The next tutorial in this series is Tables and Relationships.
12:18 Spoken Tutorial project is a part of the Talk to a Teacher project,
12:24 supported by the National Mission on Education through ICT, MHRD, Government of India.
